REFBIGERATOB Duernasr Box.

Applcation'led February 1,3, .19.24. Serial No. 692,454.

This invention relates toa refrigerating ^)ox or receptacle intendedmore particularly for use in butcher shops, or other storesv or shopsselling perishable goods, the invention having more parli cularreference to a box of this sort in which the goods or articles may beexposed to view. i

The invention has for an object to provide a novel and improvedrefrigerating box ot this sort, a further object relating to theprovision of means for varying the effective size of the box.

For 'further comprehension of the inven tion, and of the objects andadvantages thereof, reference will be had to the following descriptionand accompanying drawing, and to the appended claims in which'theVariousnovel features of the invention are more particularly set forth.

Fig. 1 of the drawing is a perspective view showlng nay-,improvedrefrigerating box.

Fig. 2 is a longitudinal vertical sectional view thereof. this Viewbeing taken on the line 2-2 of Fig. 3.

Fig. 3 is a transverse .vertical sectional view taken on the line 3--3of Fig. 2.

Figure 4 is a view similar to Fig. 2 show# ing the hinged leaves invertical position.

As here embodied myimproved box com-k 'prises the bottom 10 which may beprovided with short legs or feet .11, and fromwhich the side walls 12and the end walls 13 extend upwardly. Formed in the box, at opposite iends thereof, are the horizontally alined shelves 15 which extend fromside to side of.

the box, the space between these shelves being traversed by a number ofrods 16, which in conjunction with the shelves form a horizontalpartition and divide the box into a top compartment to receive the meator other material, and a bottom compart' ment to receive the ice forcooling.

Above the partition thus formed, the front walls of the box are formedof a number of glass panes 18 set in suitable frame pieces, the` top ofthe box being formed in part by `like glass panes 19, and in part by theinclined glass doors which are hinged to the rearwall of the box to giveaccess to the top compartment. The end walls of the box, above "theshelves 15 may likewise be formed of glasspanes 20.

In case it is not desired to utilize the full j area of the topcompartment the latter,and

` may be decreasedin size. As here shown the also the bottom compartmentfor the ice,

'unison a sprocket chain 33 maybe looped 1 elements will be proportionedso thatvmove# 'as defined in the appended claims.

shelves 1,5 have leaves 25 hinged, to their adjacent edges as at 26,these leaves being normally sunk in shallow recesses in thc shelves andbeing of a size andshape to form, when swung tovertica'l position.partitionsldividing the topl compartment into centre and end sections.4Extending `long itudinally through the box, below the shelves 15, areseveral, as here shown four, screw shafts 30 on which are mounted theadjustable wall velements 3l which 'normally lie against the end Wallsof the box, but which may be adjusted to a positionl at the inner endsof the shelves 15 as shown in... dotted are vertically alined with theleaves 25 when the latter are adjusted to vertical arrange ment. Torotate the screw shafts 30 in over sprocket wheels`34 on the individualshafts 30, one of the shafts havin itsend extended through the lend wallo the box as at 30 to receive a suitable turning tool. To swing theleaves 25 from horizontal to vertical positions they have worm gearsegfments 8G fixed to their hingepintles, which wormv gear segments areengaged by the worm pinions 37I on a shaft 38 extending along the rearwall and which is operated from, the last named of the shafts 30 bymeans of a chain 39 looped over sprocket wheels on the respective-shafts 30 and 38. As` will be understood, the various operating ment ofL the wall elementsY 31 across the v shelves will result in swinging theleaves 25 through arcs of ninety degrees. The shelves `15, wall elements31, and leaves 25, may be' constructed in any suitable manner to resistthe passage of heat.

While I have -illustrated and described a preferred embodiment of myinvention it is to -be understood that I do not limit myself to theprecise construction herein shown, and

might be made therein without departing from the spirit and Iscope oftheinyentionr Having thus described my invention what I claim as new anddesire to protect by Letters Patent of the United vStates is as followsi 1. A refrigerating' box having shelves formed atone end thereof havingshallow recesses, leaves normally sunk in the recesses of said shelvesand hinged to 'the adjacent v lines in Fig. 2, in which latter positionthey roo that various changes and modifications l ments normally'arranged Jadjacent the endsf. 'ofl the box and adapted foradjustment-jte positions under the said adjacent 'edgesof endsofzsai'd"shelves, adjustable Wall eleinents-'nermallyvau'rangjfed'adjzrx'cexllt the 'ends of the box and adaptedforadjustment to positions under'the said adjacent edges-of saidshelves.

2. A refrigeratingv *box f having shelves 3formed. at one e'ndV thereofhaving shallow recesses, leaves normally. sunk 'in -therecesses of saidshelves and hinged tot'he adjacentends of said shelves,adjustable-Wall'el'esaid shelves, and means for moving said walls andswingmg sald shelves 1n unison.

3. In a refrigerating box, apair of shelves at the ends of the boxhaving'shallowy re casses, rods connecting adjacent edges of theshelves, leaves normally sunk in the recesses of said shelves :andhinged to the said ad- "shafts and said leaves whereby rotation 'of`the' shafts swings the said leaves.

Intestimony whereof I have allixedl my signature.
